GPM Examines Upgraded Hurricane Leslie

GPM Examines Upgraded Hurricane Leslie
The GPM core observatory satellite passed above hurricane Leslie on October 3, 2018 at 7:33 AM EDT (1133 UTC). Leslie had just been upgraded to a hurricane by the National Hurricane Center (NHC). GPM's Microwave Imager (GMI) instrument collected data that revealed light to moderate convective rainfall in Leslie's clearly evident eye wall. Very little precipitation was shown by GPM in the center of the hurricane's nearly circular eye. Algorithms developed by NASA's Precipitation Measurement Missions (PMM) science team indicated that rain was falling at over 1.8 inches (45.7 mm) per hour within

GPM Sees Walaka Becoming A Powerful Hurricane

GPM Sees Walaka Becoming A Powerful Hurricane
The GPM core observatory recently had a couple good looks at tropical storm Walaka as it was intensifying into a powerful hurricane. GPM passed directly over tropical storm Walaka when it was located south of the Hawaiian islands on September 30, 2018 at 8:38 AM HST (1838 UTC). Data collected by GPM's Microwave Imager (GMI) and Dual-Frequency Precipitation Radar (DPR) instruments showed that Walaka was well organized and very close to hurricane intensity. GPM's Radar (DPR Ku Band) data revealed intense convective storms in a large feeder band that was wrapping around the tropical storm's

GPM Views Cat. 2 Typhoon Trami Moving Towards Japan

GPM Views Cat. 2 Typhoon Trami Moving Towards Japan
View fullscreen in STORM Event Viewer Once a Category 5 Super Typhoon, Trami has become rooted in place due to a lack of steering flow. This has caused the storm to deplete the warm waters beneath it and it has since weakened to a Category 2 with maximum winds of 90 knots. It maintains a broad eye and once it begins moving again, is likely to reintensify at least somewhat as it zooms northeastward over the Ryukyu Islands and into the southern coast of Japan. Wind impacts are likely to be exacerbated by its forward speed and current forecasts expect it to have widespread impacts in a region

GPM View Hurricane Rosa in the Eastern Pacific

GPM View Hurricane Rosa in the Eastern Pacific
The GMI overflight here shows a clear center of circulation with much of the intense convection on the south side of Hurricane Rosa, a Category 1 storm with winds of 75 knots. It is expected to continue intensifying over the next couple days before it runs into strong shear and cooler waters off the Baja California coast. Forecasts suggest it will make landfall in Northern Baja as a tropical storm, with its primary impacts being heavy rainfall and flash flooding over the Desert Southwest.

Super Typhoon Trami's Rainfall Examined By GPM

Super Typhoon Trami's Rainfall Examined By GPM
The GPM core observatory satellite probed super typhoon TRAMI when it traveled above the northwestern Pacific Ocean on September 24, 2018 at 1203 UTC. At that time TRAMI had maximum sustained winds estimated at 130 kts (150 mph). This image shows rainfall measurements that were made using data collected by GPM's Microwave Imager (GMI) and Dual-Frequency Precipitation Radar (DPR) instruments. GPM's GMI showed the locations of extremely heavy rainfall in the super typhoon's well defined circular eye. GPM's radar (DPR Ku Band) coverage was limited because it's swath only included storms on the

Using GPM Data for Disasters and Risk Management

GPM Applications Banner: Disasters
Monday, September 17, 2018
Too much or too little rainfall can have significant impacts on populations around the world. As population and global temperatures increase, it is crucial to understand what locations will become more vulnerable to extreme rainfall and drought and the subsequent natural hazards (e.g., landslides) and risks (e.g., lose of property) they impose. Satellites allow us to monitor changes in the precipitation, especially over oceans and regions where ground-based data are sparse. With its near-real-time precipitation estimates and near global coverage, GPM serves as an essential tool for assessing

Using GPM Data for Development and Public Health

GPM Applications: Health
Monday, September 17, 2018
Precipitation extremes, from heavy rainfall to droughts, pose great risks to a country’s economic development and human health. Standing water and flooding resulting from heavy rainfall has created societal vulnerabilities to vector and waterborne disease outbreaks such as malaria, schistosomiasis, cholera, and chikungunya, among others. Drought and extreme heat conditions have been associated with a wide range of health hazards including degraded air and water quality. These meteorological extremes also impact the growth of cities such as damaging transportation networks and infrastructures

Hurricane Florence Makes Landfall, Brings Torrential Rains and Record Flooding to the Carolinas
Over the weekend #HurricaneFlorence brought torrential rains and record flooding to the Carolinas.

GPM Observes Dangerous Super Typhoon Heading Toward The Philippines

GPM Observes Dangerous Super Typhoon Heading Toward The Philippines
The GPM core observatory satellite has recently provided very useful information about super typhoon MANGKHUT in the western Pacific Ocean. A few days ago MANGHUT battered the Marianas Islands. MANGKHUT's destructive winds pounded the island of GUAM causing power outages and it's extremely heavy rainfall caused flash floods. The GPM core observatory satellite passed over super typhoon MANGKHUT on September 11, 2018 at 0407 UTC when it was west of GUAM. GPM's Microwave Imager (GMI) and Dual-Frequency Precipitation Radar (DPR) collected data showing that MANGKHUT was a large and very well
